Abstract (en)

[origin: EP0903644A2] A toner cartridge (1) contains a photoconductive drum (49) having a central shaft (47). Gear (145) turns with the drum and has a stud (602). A coil spring (604) is mounted on the stud to form a spring clutch which is unwound by the rotation of the drum during imaging. Alternatively, a flat frictional surface is pressed against the side wall (600b) of the gear. Both contact areas have a light grease. The drag forces provide accurate, smooth operation during imaging. <IMAGE>
